the leveling device comprises an adjusting platform 19, two telescopic supporting legs 20 and a joint supporting leg 21, wherein the adjusting platform 19 is of a disc structure with a hole at the center, the standard metal measuring device 2 penetrates through the center of the adjusting platform, and the adjusting platform 19 is integrally formed on the outer wall surface of the standard metal container. The two telescopic legs 20 and the two joint legs 21 are arranged at the bottom of the adjusting platform 19 in a circular array, and the bottoms of the telescopic legs 20 and the joint legs 21 are fixed on the upper surface of the lifting platform 1.
The telescopic leg 20 includes a threaded upper column sleeve, a threaded lower column sleeve, a screw rod column and an adjusting bolt, the threaded lower column sleeve is fixedly mounted on the upper surface of the top plate 102, the threaded upper column sleeve is fixed on the lower surface of the adjusting platform, and two ends of the screw rod column are respectively in threaded connection with the threaded upper column sleeve and the threaded lower column sleeve. The adjusting bolt is integrally formed with the central position of the screw post. Through using calliper to clip adjusting bolt and rotate, then just can drive the screw rod post and rotate to realize the vertical adjustment of flexible landing leg.
The joint support leg 21 includes a joint seat and a joint column, the joint seat is fixed on the upper surface of the top plate 102, the top end of the joint column is fixed on the lower surface of the adjusting platform, a ball hinge hole is arranged on the upper surface of the joint seat, a ball head is integrally formed at the bottom of the joint column, and the ball head is rotatably mounted in the ball hinge hole, so that a rotatable connection relationship is formed between the joint column and the joint seat.
As can be seen from the above, the two telescopic legs 20 are used in cooperation to adjust the standard metal measuring device 2 to a horizontal state, and when the two telescopic legs 20 are used for height adjustment, the joint leg 21 needs to rotate around at a small angle to cooperate with the telescopic legs to achieve the purpose of leveling the standard metal measuring device 2.
In summary, the intelligent calibrating device for the fuel dispenser provided by the invention has the following advantages:
1. the electronic tag and the automatic identification technology thereof are adopted, so that the corresponding gun number and the oil product number are automatically filled when the verification result is generated, the working efficiency is improved, the cheating prevention effect is realized, the intelligent level of a standard metal measuring device used for verifying the fuel oiling machine is effectively improved, and the accuracy of the verification result is improved; the labor intensity of verification workers is reduced, and the verification work efficiency is improved; and the supervision and management of the verification process and the verification result and the comprehensive application of data are enhanced.
2. After the verification is finished, the anti-static grounding clamp is taken down by an operator, the verification device is pushed to a tank area of a gas station, and the tank returning operation is carried out on oil products. Before returning the jar, operating personnel will prevent that static ground connection presss from both sides to be connected to on the other ground connection band iron of oil tank district oil discharge port, main control circuit detects prevents that static ground connection is normal, operating personnel clicks the solenoid valve button of opening in the display interface returns jar operation flow, the solenoid valve is opened, the oil buries the oil tank along the oil discharge hose flow in filling station, if prevent static ground connection and connect inefficacy, then click the solenoid valve button of opening at system display interface and do not have the reaction, oil discharge can not go on, need to get rid of and prevent that static ground connection fault rear can continue to go on, go on with the safety of guaranteeing that the oil returns jar process, prevent the oil explosion accident that causes because of electrostatic discharge.
3. According to the invention, the traditional standard metal measuring device 2 is arranged on the lifting platform 1 with hydraulic control, so that when an operator returns the oil for verification to the tank, the lifting platform 1 can lift the standard metal measuring device 2 by 30-50 cm integrally, the height of the pipe orifice of the liquid discharge pipe is increased to adapt to the height of the oil discharge port of the oil tank of the gas station, the liquid discharge operation is carried out in a safe and reliable environment, and the oil leakage is avoided.
4. The depth and the disc surface diameter of the overflow cover 5 at the top of the standard metal gauge 2 are increased to avoid that oil splashing or a large amount of foam generated during diesel oil filling (especially more foam generated during diesel oil filling when the temperature is lower in winter) is easily formed due to the pressure of an oil gun in the oil filling process, so that an operator is forced to control the flow rate of the oil gun to be minimum, even the oil gun is forced to be closed under the pressure to suspend oil filling, and the oil is continuously filled after the foam is dissipated, but the operation process has the defects of serious influence on the detection result and the like, so that the oil filling operation in the whole detection process can be smoothly completed at one time, and the defects that the oil gun flow rate is too small, the gun jumps halfway and the oil splashing causes the distortion of the detection result are avoided
5. By installing the solenoid valve 8 on the oil drain pipe 7 to replace the conventional manual ball valve, the advantages are that: after the oil is totally returned to the jar, rethread control switch closed solenoid valve 8 after not having the residual oil in the jar, improves the convenience and the reliability of opening and closing the operation, avoids opening incompletely because of the ball valve that manual operation probably leads to, and the extension oil returns jar latency or because of the ball valve is closed not tight, and causes the oil to run out and leak when detecting to refuel next time.
